我使用EasyWechat尝试开发了一个第三方平台，然后会帮助本地商户或公众号运营一些活动，如何在公众号授权对接后快速的将公众号粉丝数据同步到本地数据库方便运营？我先前的想法是用户有交互的时候再触发同步，目前是使用的手动方式和命令行方式，手动方式如下：

/**
     * 同步
     */
    public function sync()
    {
        $account = $this->request->param('account', 0, 'intval');
        $account = AccountService::getDataById($account);
        if (empty($account)) {
            $this->error('参数错误');
        }
        //页码
        $page = $this->request->param('page', 0, 'intval');
        $page_size = 50;
        //微信实例
        $wechat = WechatService::applicationInit($account);
        
        //先从缓存中读取
        $fans = cache('wechat_fans_'.$account->id);
        if (!$fans) {
            echo '从腾讯拉取';
            //从腾讯拉取第一页
            $datas = $wechat->user->lists();
            $total = ceil($datas['total'] / $datas['count']);
            $fans = $datas['data']['openid'];
            for ($i = 1; $i < $total; $i++) {
                $datas = $wechat->user->lists($datas['next_openid']);
                $lists = $datas['data']['openid'];
                foreach ($lists as $k => $v) {
                    array_push($fans, $v);
                }
            }
            //设置缓存
            cache('wechat_fans_'.$account->id, $fans);
        }
        foreach ($fans as $k => $v) {
            if ($k <= $page * $page_size) {
                continue;
            }
            if ($k > ($page + 1) * $page_size) {
                return $this->success('更新下一页', url($this->request->controller().'/sync', ['account' => $account->id, 'page' => $page + 1]));
            }
            echo '同步'.$k.'成功<br/>';
            try {
                UserService::syncDataByServer($account, $v);
            } catch (\Exception $e) {
                echo '同步'.$k.'出错<br/>';
                continue;
            }
        }
        //删除缓存
        cache('wechat_fans_'.$account->id, null);
        return $this->success('同步完成', url($this->request->controller().'/index', ['account' => $account->id]));
    }

这种使用分页同步在浏览器执行的方式速度非常慢，大约几万粉丝都要跑很久，然后跟这个类似的我写了一个命令行方式，执行也很慢。

<php
namespace app\wechat\command;
use app\wechat\service\AccountService;
use app\wechat\service\WechatService;
use app\wechat\service\UserService;
use think\console\Command;
use think\console\Input;
use think\console\Output;
use think\console\input\Option;

/**
 * 同步用户命令
 * Class SyncUser
 * @package app\wechat\command
 */
class SyncUser extends Command
{
    /**
     * 命令行配置
     */
    protected function configure()
    {
        //设置命令名称及描述
        $this->setName('Wechat:SyncUser')
            ->addOption('account', 0, Option::VALUE_REQUIRED, '账号ID.')
            ->setDescription('同步公众号用户');
    }

    /**
     * 命令
     * @return int|null|void
     */
    protected function execute(Input $input, Output $output)
    {
        ini_set('memory_limit', '1024M');
        if (!$input->hasOption('account')) {
            $output->writeln("请输入账号");
            return null;
        }
        $account = $input->getOption('account');
        $account = AccountService::getDataById($account);
        if (!$account) {
            $output->writeln("参数错误");
            exit;
        }
        //微信实例
        $wechat = WechatService::applicationInit($account);
        //先从缓存中读取
        $fans = cache('wechat_fans_'.$account->id);
        if (!$fans) {
            $output->writeln("从腾讯拉取粉丝");
            //从腾讯拉取第一页
            $datas = $wechat->user->lists();
            $total = ceil($datas['total'] / $datas['count']);
            $fans = $datas['data']['openid'];
            for ($i = 1; $i < $total; $i++) {
                $datas = $wechat->user->lists($datas['next_openid']);
                $lists = $datas['data']['openid'];
                foreach ($lists as $k => $v) {
                    array_push($fans, $v);
                }
            }
            //设置缓存
            cache('wechat_fans_'.$account->id, $fans);
        }
        foreach ($fans as $k => $v) {
            try {
                UserService::syncDataByServer($account, $v);
            } catch (\Exception $e) {
                $output->writeln("同步{$k}出错");
                continue;
            }
        }
        //删除缓存
        cache('wechat_fans_'.$account->id, null);
        $output->writeln("同步完成");
    }
}

求教各位大神有没有比较好的方案。麻烦详细些，本人不是专业的程序员，太简略了看不懂。谢谢！
